The clock was winding down in Team USA's blowout exhibition victory Thursday night against the John Calipari-coached Dominican Republic team when Hornets rookie and one-year Kentucky star Anthony Davis spotted up for a 3-point shot from the right elbow.' Davis launched a high rainbow that swished through the net, was fouled, then turned toward his college coach, thumped his chest and yelled at him good-naturedly. "He was telling me," Calipari said afterward, "that I never let him shoot 3s at Kentucky." Perhaps that's because Davis's one-year 3-point shooting stats left much to be desired: 3-of-20 from beyond the stripe. But Davis' play in the fourth quarter — all but two seconds of the 10-minute period — provided a glimpse of what's to come for him, and a glimmer of hope for the U.S. Olympic basketball team, which is two weeks from beginning defense of its gold medal in the London Games. Davis, once some procedural matters are finished, will be joining Team USA, replacing injured power forward Blake Griffin, who'll miss the Olympics because of a torn meniscus in his left knee.
